Bulevirtide has been recently conditionally approved by the European Medicines Agency for the treatment of Chronic Hepatitis Delta, but the ideal duration of therapy is unknown. Here we describe the first case of cure of Hepatitis Delta following 3 years of Bulevirtide monotherapy in a patient with compensated cirrhosis and esophageal varices. During the 72-week off-Bulevirtide follow-up, virological and biochemical responses were maintained. In the off-therapy liver biopsy, intrahepatic HDV RNA and Hepatitis D antigen were undetectable, <1% hepatocytes were Hepatitis B surface antigen positive while hepatitis B core antigen was negative. Grading and staging improved compared to pre-treatment biopsy.
